Guide To The Causes Of A Toothache

Abscessed Tooth

An abscessed tooth occurs when a pocket of pus forms in a portion of the tooth. Abscesses can form in basically any part of the tooth, though they might be more likely in teeth with cavities. The pus is the body's response to a bacterial infection inside the tooth where there is a nerve. When the pus and bacteria invade the tooth with nowhere to go, the pressure builds until the nerve becomes compressed, causing pain ranging from moderate to severe. It might throb or shoot toward the neck and ear. Abscessed teeth can become life-threatening if the infection isn't treated. A periapical abscess forms at the tip of the root of the tooth. A periodontal abscess forms not on the tooth itself, but the gum immediately beside the root. A gingival abscess forms on the gums. Pain from an abscessed tooth tends to occur suddenly, and it builds over time. It might be worse when individuals lie down, eat, or try to brush their teeth. The infection might also cause facial swelling, a fever, and swollen lymph nodes.
